Guitar Hero is awesome (and Rockband-don’t worry!) and Microsoft Research are pretty great too. So what happens when you put the two together? I’ll tell you…playing Guitar Hero without a controller!
This would definitely reduce the amount of space that all the guitars take up, and make it easier to carry them around (should you wish). They also show the technology being used to control an MP3 player whilst out jogging…just move a finger to skip, pause, play etc…something that would definitely take off 
Again, more great work from Microsoft Research
